A WORLD ON PAUSE. Now we are moving to the most struggling period of our life.Yes we are with COVID -19.Let's know more about COVID-19 . Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, the coronaviruses cause respiratory tract infections that can range from mild to lethal. Mild illness include some causes of the common cold (which has other possible causes predominantly rhinoviruses),while more lethal varieties can cause SARS,MERS,and COVID -19.Symptoms in other species vary:in chickens, they cause an upper respiratory tract diseases, while in cows and pigs they cause diarrhoea. Human coronaviruses, first characterized in 1960's are responsible for a substantial proportion of upper respiratory tract infections in children. Since 2003,atleast 5 new human coronaviruses have been identified, including the severe acute respiratory syndrome coronavirus ,which caused significant morbidity and mortality. Now ,Let's know about Corona's family VIRUS CLASSIFICATION:(UNRANKED) : VIRUS ;REALM: RIBOVIRIA ;PHYLUM: INCERTAE SEDIS ;ORDER: NIDO VIRALES ;FAMILY: CORONA VIRIDAE;SUBFAMILY :ORTHOCORONAVIRINAE.These are enveloped viruses with a positive sense single stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, one of the largest among RNA viruses. They have characteristic club-shaped spikes that project from their surface , which in electron micro graph create a image reminiscent of the solar corona from which their names derives. So,now we learn a few things about COVID-19.This is not enough about CORONA. Many other information are yet .But now I'm concluding my article by saying STAY HOME , BE SAFE, WE WILL OVERCOME CORONA THASNIM.A.S IX സി.കെ.സി.എ‍ച്ച്.എസ്,പൊന്നുരുന്നി ത്രിപ്പൂണിത്തുറ ഉപജില്ല എറണാകുളം അക്ഷരവൃക്ഷം പദ്ധതി, 2020 ലേഖനം  സാങ്കേതിക പരിശോധന - Anilkb തീയ്യതി: 17/ 04/ 2020 >> രചനാവിഭാഗം - ലേഖനം
